The 2.256-mile, 13-turn circuit that incorporates a section of airport runway again will challenge drivers and provide lots of action for spectators.

The 90-degree first turn is augmented by a pair of hairpins at the north and south ends of the course. There also are two long straights for drag racing. The layout was new for the July 2011 race.Edmonton City Centre Airport has played host to an Indy car race since 2005, with Scott Dixon, Will Power and Sebastien Bourdais winning twice.

Race Review

Carlos Munoz relies on Andretti Autosport crew members to prepare the No. 26 Team Dialy-Star car for each session on the racetrack. On Lap 14 of the Edmonton 100, the 20-year-old pace-setter relied on them for a quick tire change.

It's not often that Firestone Indy Lights races require a switch from rain tires to slicks -- and vice versa -- but a rainstorm 30 minutes before the green flag of the 40-lap race on the 2.224-mile, 13-turn City Centre Airport circuit necessitated Race Control to declare a wet start.

As the racing line dried under the tires of the 11 cars and the sun did its part, drivers began peeling onto pit lane for a set of Firestone slicks on Lap 12. Munoz's crew got him out without losing a lap, and he regained the point on Lap 17.

The rest was academic as the pole sitter went on to his first Firestone Indy Lights victory. His previous best was second at Belle Isle and Indianapolis.

"It was a crazy race with rain," said Munoz, wrapped in the Colombian flag in Victory Circle. "Once it was dry, the car was unbelievable. The guys did an awesome job all weekend; first in practice, first in qualifying, first in warm-up and now the race. It’s impossible to do any better. And the pit stop, the guys just did an incredible job. I’m really happy to get my first win."

Sebastian Saavedra, driving the No. 27 Team AFS car, was 8.3453 seconds back and Esteban Guerrieri finished third in the No. 11 Pistas Argentinas/Sam Schmidt Motorsports with Curb Agajanian car. It was the sixth podium finish of the season for Saavedra, who moved to second in the championship standings. Guerrieri, the 2011 race winner who notched his seventh podium of the season, holds a 27-point lead heading to the event in two weeks in Quebec.

It was the 15th 1-2 finish by teammates in Firestone Indy Lights history and the third for Andretti Autosport.

"We knew that the points were very important," he continued. "Right now we’re second in the championship and that’s incredible for us. And congratulations to Carlos. He was in a race of his own."
